Use My.Computer.Network.DownloadFile In An Access Db?
Mar 24, 2012I'm trying to download a file from the internet by clicking a button in MS Access.
I'm trying to use My.Computer.Network.DownloadFile as described here: [URL]
Private Sub Command2_Click()
My.Computer.Network.DownloadFile("http://www.example.com/temp/xml_test.xml", "C:xml_test.xml")
End Sub
but the 'Microsoft Visual Basic for Applications' IDE that I'm typing this into seems to have no idea what I'm talking about (text just turns red).
Can I just not do this through the built in VB editor or can I simply load a library or something to make it work?
Sorry but I'm very new to VB and to Access so search results are not specific enough for me to understand - lord knows I've tried.
I'm using Access 2010 but the DB was created in an previous version - not sure if that matters.

Sockets - Check That If Another Computer In The Network Send Some String Data To The Listener Computer?
Mar 19, 2012i have a task to create a TCP Server (a program that is listening on its network card interfaces for incoming data stream).I have search on the internet and i found that i can use two methods : Socket or TCPListener class.I have created an example for Socket class, but i wondering how could i test it? I need to check that if another computer in the network send some string data to the listener computer , then this message should be displayed.Here is the example from microsoft that i am using for TCP Server using Socket:
Public Shared Sub Main()
' Data buffer for incoming data.
Dim data = nothingc[code]....
But it does not work because of the PORT setting.If in the TCP Server i have "Dim localEndPoint As New IPEndPoint(ipAddress, 0)" the client crashes, but if i change the port from any (0) to 11000 for example,the client works fine.Do you know why?
Later edit2:Maybe i should have started with this question:Which method is recommended for my scope?asynchronous or synchronous method ?
VS 2008 My.Computer.Network.Ping() Cannot See Network Under Windows 7
Nov 18, 2011I have a .NET 2.0 *.dll that calls My.Computer.Network.Ping(). The *.dll is then run out of an *.exe via AppDomain.CreateDomain() and Invoke(). The problem is that this works just fine under Windows XP but under Windows 7, I get an exception saying that no network connection is available. I tried the Ping() call out of a small console application under Windows 7 and it works just fine.

Developing A Computer Application Designed To Monitor The Network And CPU Statistics On A Computer?
Jan 29, 2009I am developing a computer application designed to monitor the network and CPU statistics on a computer remotely. The monitored computer would have my program installed and the monitoring computer would display, in a form, the information being sent from the remote client.The application does not send any information regarding packets, user names, passwords, etc. It is solely meant for monitoring CPU performance and Network resources remotely.
What would be the best method to send this information over to my host machine?I am programing in Visual Studio 2008 on windows XP. The client machine is also XP. I know this sounds a little shady, but it is required for my little business (http://www.iquorum.net) to monitor what and when something happens on our machines when I and my employees are away.

View 2 RepliesStream Video From Network PC Via Webcam?
Jan 18, 2006I have a little Logitech USB Webcam that I have attached to a laptop and I want to be able to view a video stream from it. I already gathered it will need to be a client/server model...and I probably need to use TCP/IP and/or Winsock (if its still even used)...
how to really approach this application as far as the video capture process? I don't have a need to really record video in any way so if i can just "preview" the video thats fine, although recording would be a neat bonus.
I read into the Windows Image Aquisition libraries and they seemed to be the right thing...but I wasn't so sure about the cross-network half of the equation.

View 3 RepliesCommunications :: Find Device On Network By Its Mac Address?
Feb 6, 2009I have a small embedded web server and to setup its network parameters I use a serial port, however this is giving me a lot of trouble due to USB to serial adapters (in some computers work in other doesn't).
However the other day I saw that Buffalo has a little program to find their NAS boxes (or network drives) when you don't know their IP address or got the wrong one so I assume they do it by looking for mac addresses.Is there any way of doing this with VB 2005 or higher? Basically I don't know the IP of the embedded server so I need to find it on a network, how do I find it?
a) I could do a general IP scan assuming it is on the same subnet than the host computer
b) if it has a different subnet... a general IP scan is not going to work, is it?
Communications :: Program Stalling On Network Reading?
Oct 8, 2008I am playing with network sockets as I need to work on a client-server application. So I have tried this simple code from VS help:
Code:
Dim tcpClient As New TcpClient()
'The following line do not belongs to original code 'But I needed to add it as debugger told me that 'I couldnt getStream from closed sockets
tcpClient.Connect("127.0.0.1", 8000)
Dim netStream As NetworkStream = tcpClient.GetStream()
If netStream.CanWrite Then
[code]....
So, I supposed that the code above would write the message to the loopback IP (127.0.0.1), it would be kept in the network buffer and would be spited out when it readed the same loopback IP. However, when it gets the line whre it should read the stream, the program just stalls and keep reading it forever. I have tested the stream with as if it was just awaiting for something to read. I have tested the stream with getStream.DataAvailable and it returned me False, what makes me guess that the data is NOT being properly written to the IP.
Firstly I thought that it could be something with the loopback IP, then I tried to provide the machine local IP (192.168.2.25) but I got the same behavior: code stalls...
Communications :: Could Lost Packets Interfere With Network Operation
Jul 29, 2008At my workplace I have been developing a server/client application which receives on port 8000 and sends on 8001. We do not have any other applications that use these ports, but we do have an application that accesses an SQL database in which part data is stored.
When I am doing testing on the application, if the server were to crash while the client app was sending a packet, could this lost packet cause issues with the network at all?I ask because for some reason we have been receiving connection timeout errors from the application that stores our product data, but we haven't made any changes or started running any new jobs on the network that I am aware of.
Communications :: Write A Program To Ping Computers On Network To See If They Are Turned On?
Jul 4, 2008I am trying to write a program to ping computers on my network to see if they are turned on. So far i have the following:
Code:
If My.Computer.Network.Ping("192.68.0.5") Then
MsgBox("Computer is on.")
Else
MsgBox("Ping request timed out.")
End If
If i use ip addresses, this works fine but i would rather use hostnames due to the ip addresses being dynamic (something which is outside my control). Using the hostname, it reurns "Computer is on" if the ping is successful, but if the hostname cannot be found, instead on returning "Ping request timed out", an error occurs as follows:
A first chance exception of type 'System.Net.NetworkInformation.PingException' occurred in System.dll

Comparison To A File On A Different Computer On The Same Network
Jan 4, 2012I have a computer that takes in a barcode through a Visual Basic program on one computer and I want to be able to compare that barcode as a String to data on a different computer on the same network by ethernet connection where the data is stored in an Excel 2010 file (.xlsm) in Column A in a workbook called 'Data.xlsm'. Before the data is allowed to be saved or used further in the program on the first computer, I would like for the comparison to happen.
Some more details that you all may or may not need.
Computer 1 (where barcode is scanned): Windows 7, Office 2010
Computer 2 (where data file is stored): Windows XP, Office 2007
